Error while running event on_player_created (ID 24) Chainsaw/control.lua:60: attempt to index local 'tool_inventory' (a nil value)
Factorio 0.14.23 Chainsaw_1.14.4
I fixed that in the 1.15.1 version, you could just downloads the latest version manually and copy what I did at that line to fix it. I'm not realy supporting 0.14 anymore sorry.
